After kind equipment sets charging current as 1A, need to coordinate the adapter of 1A to use.If using the adapter of 2A, equipment is also
It is to be charged with 1A, is unable to fully the charging ability using 2A adapters.If using the adapter of 0.5A, equipment is still
It is charged with 1A, then being likely to damage adapter.
The patent of Publication No. 103401421 discloses a kind of control circuit of Boost converter.The disadvantage is that only real
Existing boost in voltage function, can not automatic identification front end power supply power supply ability degree of strength, can not be according to front end power supply power supply energy
Power adjusts rear end charging current.

The charging ability of charger be divided into it is strong, in, weak three grades.If the real-time voltage value of charger is more than second voltage
Threshold value, then the charging ability of charger is strong.If the real-time voltage value of charger is less than first voltage threshold value, the charging of charger
Ability is weak.If the real-time voltage value of charger is between first voltage threshold value and second voltage threshold value, the charging energy of charger
Power is medium.Such as, the specification of charger 1 is output voltage 5V, output current 2A, and charging current slowly increases from 0 reaches setting
Maximum value, the real-time output voltage of charger 1 is all between 4.5V-5V, then the charging ability of charger 1 is strong, to make full use of
The charging ability of charger 1 should use output current as big as possible to power for charging load；The specification of charger 2 is output
Voltage 5V, output current 1A, charging current from 0 slowly increase to a certain current value when, the real-time output voltage of charger 2 may
Between 4V-4.5V, then the charging ability of charger 2 is medium, and charged state is unstable, in order to ensure charging safety and can
By property, it should suitably reduce output current；The specification of charger 3 is output voltage 5V, and output current 0.5A, charging current is from 0
When slowly increasing to a certain current value, the real-time output voltage of charger 3 is less than 4V, then the charging ability of charger 3 is weak, charging
State is extremely unstable, in order to ensure charging safety and reliability, should output current reach can bear maximum value when,

Voltage is much smaller than the zero load voltage of charger, and the charged state of charger is extremely unstable.Therefore, in order to protect charger,
When charger real-time voltage reaches first voltage threshold value, emergency descent charger outputs current to zero, then gradually incrementally charges
The output current of device damages charger with charger free because of overcurrent.
When charger real-time voltage value is between first voltage threshold value and second voltage threshold value, the charging of charger is indicated
